  @article{weber20182016novel, abstract = {Magnetic Particle Imaging (MPI) offers several methods for encoding magnetic materials in three-dimensions. The complexity of the imaging device in MPI using a field free line (FFL) is the biggest challenge in realizing such devices. This is especially the case for systems featuring large bores, high gradients or high temporal resolution. In this work, we suggest a novel Halbach cylinder based field generator that is able to generate an FFL with a gradient of 5 T/m. By rotating the Halbach array, FFL projections can be acquired. Furthermore, just one static drive field coil is needed for two-dimensional imaging. The presented concept could combine high gradient strength and high temporal resolution with minimum space requirements for FFL-MPI imaging in the future. Int. J. Mag. Part.

  @article{Graefe2016b, abstract = {Magnetic Particle Imaging is a new medical imaging modality, which detects superparamagnetic iron oxide nanoparticles. The particles are excited by magnetic fields. Most scanners have a tube-like measurement field and therefore, both the field of view and the object size are limited. A single-sided scanner has the advantage that the object is not limited in size, only the penetration depth is limited. A single-sided scanner prototype for 1D imaging has been presented in 2009. Simulations have been published for a 2D single-sided scanner and first 1D measurements have been carried out. In this paper, the first 2D single-sided scanner prototype is presented and the first calibration-based reconstruction results of measured 2D phantoms are shown. The field free point is moved on a Lissajous trajectory inside a 30 x 30 mm2 area. Images of phantoms with a maximal distance of 10 mm perpendicular to the scanner surface have been reconstructed. Different cylindrically shaped holes of phantoms have been filled with 6.28 μl undiluted Resovist. After the measurement and image reconstruction of the phantoms, particle volumes could be distinguished with a distance of 2 mm and 6 mm in vertical and horizontal direction, respectively.}, author = {Gräfe, K. and von Gladiß, A. and Bringout, G. and Ahlborg, M. and Buzug, T.M.}, journal = {IEEE Transactions on Medical Imaging}, keywords = {AhlborgMandy BringoutGael BuzugThorsten GladissAnselm GraefeKsenija IMT SingleSided}, number = 4, pages = {1056-1065}, title = {2D Images Recorded With a Single-Sided Magnetic Particle Imaging Scanner}, volume = 35, year = 2016 }

  @article{Finas2015a, abstract = {Surgical breast cancer related staging with radical axillary lymph node extraction was mandatory in past times. High morbidity and significant loss of quality of life was inevitable. By introduction of the concept of sentinel lymph node biopsy (SLNB), these adverse effects decreased. Detection of sentinel lymph nodes (SNLs) is realized by the use of dyes and radio nuclides as tracer substances. These tracers can be replaced by superparamagnetic iron oxide nanoparticles (SPIOs) in the near future. Magnetic particle imaging (MPI) guided 3-D real-time imaging and a distinct localization of SPIOs can be achieved in SLNB by the use of MPI. However, qualitative and quantitative enrichment of SPIOs in biologic tissue, in particular, the axillary lymphatic tissue is unexplored until now. We aim to prove the principle of SLNB with MPI within a healthy and than in a tumor bearing mouse model with metastatic axillary lymph nodes in breast cancer. Axillary tissue, surrounding tissues, and tissue from the whole body are analyzed with the following techniques: histology, Prussian blue staining, electron microscopy, atomic absorption spectrometry, and magnetic particle spectroscopy. We found that the SPIOs moves from the injection site through the lymph-fat tissue to the axillary region and finally into the axillary lymph nodes. SPIOs follow traces of lymphatic vessels, respecting borders, and spaces between different tissues. They accumulate near collagen fibers and distinct regions. We present our results of the approach of SLNB with MPI. Application of SPIOs and tracer detection in SNLs with MPI as a new SLNB technology could be less complex and incriminating for patient and staff and could make SLNB more accurate. To realize this approach, an MPI hand probe for intraoperative use is under construction. This will simplify SNL detection and helps to reduce axillary exploration morbidity by avoidance of intensive surgical quest. The tracer for MPI is easy to obtain and this make- the method accessible to many patients. The concept of SLNB by MPI may be applied in principle in all solid tumors.}, author = {Finas, D. and Baumann, K. and Sydow, L. and Heinrich, K. and Rody, A. and Gräfe, K. and Buzug, T.M. and Lüdtke-Buzug, K.}, journal = {IEEE Transactions on Magnetics}, keywords = {BuzugThorsten GraefeKsenija IMT LuedtkeKerstin SingleSided}, month = {feb}, number = 2, pages = 5400104, title = {SPIO Detection and Distribution in Biological Tissue - A Murine MPI-SLNB Breast Cancer Model}, volume = 51, year = 2015 }

In light of efforts to scale up imaging systems (e.g. from mouse/rat size [3-6] to rabbit size [7]) and/or to increase the size of the field of view (FOV) compared to the bore of the scanner [8], the question gains in importance how the imaging process is affected by magnetic field inhomogeneities and gradient field nonlinearities, which may deform the FFL compared to an FFL produced by idealized homogeneous/linear magnetic fields. Moreover, truncation effects are an important aspect that has so far not been studied in FFL MPI.

  @article{Buzug2012b, abstract = {Magnetic Particle Imaging (MPI) is a recently invented tomographic imaging method that quantitatively measures the spatial distribution of a tracer based on magnetic nanoparticles. The new modality promises a high sensitivity and high spatial as well as temporal resolution. There is a high potential of \{MPI\} to improve interventional and image-guided surgical procedures because, today, established medical imaging modalities typically excel in only one or two of these important imaging properties. \{MPI\} makes use of the non-linear magnetization characteristics of the magnetic nanoparticles. For this purpose, two magnetic fields are created and superimposed, a static selection field and an oscillatory drive field. If superparamagnetic iron-oxide nanoparticles (SPIOs) are subjected to the oscillatory magnetic field, the particles will react with a non-linear magnetization response, which can be measured with an appropriate pick-up coil arrangement. Due to the non-linearity of the particle magnetization, the received signal consists of the fundamental excitation frequency as well as of harmonics. After separation of the fundamental signal, the nanoparticle concentration can be reconstructed quantitatively based on the harmonics. The spatial coding is realized with the static selection field that produces a field-free point, which is moved through the field of view by the drive fields. This article focuses on the frequency-based image reconstruction approach and the corresponding imaging devices while alternative concepts like x-space \{MPI\} and field-free line imaging are described as well. The status quo in hardware realization is summarized in an overview of \{MPI\} scanners.}, author = {Buzug, T.M. and Bringout, G. and Erbe, M. and Gräfe, K. and Graeser, M. and Grüttner, M. and Halkola, A. and Sattel, T.F. and Tenner, W. and Wojtczyk, H. and Haegele, J. and Vogt, F.M. and Barkhausen, J. and Lüdtke-Buzug, K.}, journal = {Zeitschrift für Medizinische Physik}, keywords = {AhlborgMandy BringoutGael BuzugThorsten GraefeKsenija GraeserMatthias IMT LuedtkeKerstin MedimaghHanne}, note = {Schwerpunkt: Multimodale Bildgebung und Therapie}, number = 4, pages = {323-334}, title = {Magnetic particle imaging: Introduction to imaging and hardware realization}, volume = 22, year = 2012 }

As drug induced QT-prolongation can be caused by changes in the repolarisation of the ventricles, it is so far a thorough ECG biomarker of risk for ventricular tachyarrhythmias and Torsade de Pointes (TdP). Ventricular repolarisation changes not only change QT but also influence the morphology of the T-wave. In a (400 mg single dose) Moxifloxacin positive control study both, QTc and several descriptors describing the T-wave morphology have been measured. Moxifloxacin is changing two shape dependent descriptors significantly (P≤0.05) about 3 to 4 hours after a 400 mg oral single dose of Moxifloxacin.}, author = {Baas, T. and Gräfe, K. and Khawaja, A. and Dossel, O.}, booktitle = {Proceedings of the 33rd IEEE conference on Engineering in Medicine and Biology Society}, keywords = {GraefeKsenija}, month = {aug}, pages = {3796-3799}, title = {Investigation of parameters highlighting drug induced small changes of the T-wave's morphology for drug safety studies}, year = 2011 }
